Software developers are on a constant quest to improve their skills and learn new ones. Navigating the ocean of courses and certifications out there can be daunting so I have produced a guide to course providers which I have researched carefully and who provide learning relevant to the people who read this blog.
The Linux Foundation provides a range of training courses of the very highest quality, some highly specialized Linux-specific and costing in excess of $3000. However, many cost just a few hundred and many more are free!
Udacity provide a wide range of highly vocational courses in the tech space including programming, data science and computer science, as well as career training to help you get into the job you want.
